Building ParaView with the latest superbuild on commit dbfee3f64e9b64e126a2df217f0156381251aa3b with gcc-4.9.4 I get lots of repeated errors in the form of error:  
` no type named ‘ValueType’ in ‘auto’`  
and of:  
` <lambda(SrcTupleCRefT)>’, is used but never defined [-fpermissive]`  
I’ve attached a build output. ParaView 5.6 built just fine with gcc-4.9.4 for reference.

Okay I will look into fixing these in a separate MR.

@chart3388 I have opened a [merge request for VTK](https://gitlab.kitware.com/vtk/vtk/merge_requests/6400) that corrects this issue. Once merged into VTK, ParaView will update to get these corrections.

@robert.maynard - thank you. I’ll log this under an issue next time in gitlab. Also I can confirm this resolved the issue.
